Un dispositif de gestion de puissance (10) comprend une unité d'acquisition (11), une unité d'estimation (12), une unité de gestion (13) et une unité de détermination (14). L'unité d'acquisition (11) acquiert des informations DR comprenant une valeur de réduction et une période cible qui sont requises pour réduire la puissance reçue. L'unité d'estimation (12) estime, en tant que premières informations de puissance, la puissance consommée par des charges électriques (2) durant la période cible. L'unité de gestion (13) gère, en tant que secondes informations de puissance, la puissance qui peut être délivrée par une installation d'alimentation électrique (20) comprenant une installation de stockage d'électricité (21).
